# lookup\_one\_len\_unlocked(9)

filesystem helper to lookup single pathname component

## NAME

lookup\_one\_len\_unlocked - filesystem helper to lookup single pathname component

## SYNOPSIS

**struct dentry \* lookup\_one\_len\_unlocked(const char \*** *name***, struct dentry \*** *base***, int** *len***);**

## ARGUMENTS

*name*

pathname component to lookup

*base*

base directory to lookup from

*len*

maximum length *len* should be interpreted to

## DESCRIPTION

Note that this routine is purely a helper for filesystem usage and should not be called by generic code.

Unlike lookup\_one\_len, it should be called without the parent i\_mutex held, and will take the i\_mutex itself if necessary.
